According to WRIC 8 News, a new bin store has officially opened in Chesterfield County. What is a bin store?. A bin store is a type of liquidation store that sells overstocked, returned, or clearance items at set, bargain rates. It is called a bin store because merchandise is not on shelves as in grocery stores. Everything is contained in large bins that customers are encouraged to search to find what they want to purchase. It is like a treasure hunt. The bins of overstock or returned goods are sold at bargain-basement prices. Think of it like a treasure hunt as you search for items returned from Amazon, Target, Walmart, and other major retailers.
